From which artery does the anterior tibial artery arise?

The popliteal artery.

In This Section

1. From which artery does the anterior tibial artery arise?

The popliteal artery.

2. Where does the anterior tibial artery originate?

Near the inferior border of the popliteus muscle, where the popliteal artery divides into its terminal branches.

3. Through which structure does the anterior tibial artery enter the anterior compartment of the leg?

An opening in the proximal interosseous membrane between the tibia and fibula.

4. Which compartment of the leg contains most of the anterior tibial artery?

The anterior compartment of the leg.

5. What is the general course of the anterior tibial artery?

It descends through the anterior compartment along the interosseous membrane toward the anterior ankle.

6. Which structure lies immediately posterior to the anterior tibial artery in the proximal leg?

The interosseous membrane.

7. Between which muscles does the anterior tibial artery initially descend?

The tibialis anterior and extensor digitorum longus muscles.

8. Between which muscles does the anterior tibial artery descend in the distal leg?

The tibialis anterior and extensor hallucis longus muscles.

9. Which nerve accompanies the anterior tibial artery through the anterior compartment?

The deep fibular nerve, also called the deep peroneal nerve.

10. How does the deep fibular nerve typically relate to the anterior tibial artery along its course?

It crosses from the lateral to the medial side of the artery, with some anatomical variation.

11. Which veins accompany the anterior tibial artery?

The paired anterior tibial veins, which form venae comitantes around the artery.

12. What are the principal named branches of the anterior tibial artery?

The posterior tibial recurrent, anterior tibial recurrent, anterior medial malleolar, and anterior lateral malleolar arteries.

13. Which branch of the anterior tibial artery commonly ascends toward the anterior knee?

The anterior tibial recurrent artery.

14. What is the function of the anterior tibial recurrent artery?

It contributes to the genicular arterial anastomosis around the knee.

15. Where does the posterior tibial recurrent artery arise?

Usually from the proximal anterior tibial artery before it passes through the interosseous membrane.

16. Which branch of the anterior tibial artery supplies the medial ankle region?

The anterior medial malleolar artery.

17. Which branch of the anterior tibial artery contributes to the lateral malleolar arterial network?

The anterior lateral malleolar artery.

18. Which muscles receive branches from the anterior tibial artery?

Tibialis anterior, extensor hallucis longus, extensor digitorum longus, and fibularis tertius.

19. Where does the anterior tibial artery become the dorsalis pedis artery?

At the anterior ankle, approximately midway between the medial and lateral malleoli.

20. Which ankle retinacular structures does the distal anterior tibial artery pass deep to?

The superior and inferior extensor retinacula.

21. What is the approximate surface marking of the anterior tibial artery?

A line from just medial to the fibular head toward the midpoint between the ankle malleoli.

22. Which artery continues the anterior tibial arterial supply onto the dorsum of the foot?

The dorsalis pedis artery.

23. What is the main anatomical territory supplied by the anterior tibial artery?

The anterior compartment of the leg, with branches to the ankle and continuation onto the dorsum of the foot.

24. How can anterior compartment syndrome affect the anterior tibial artery?

Elevated compartment pressure can compromise arterial perfusion and produce ischemia of anterior leg structures.

25. What is the clinical significance of the dorsalis pedis pulse in relation to the anterior tibial artery?

It provides a distal assessment of arterial flow through the anterior tibial artery and its continuation.
